The Diplomat is a great spa. The his and hers loungers are well laid out, and prevent floating for most people. The water mgmt and filtration system is one of the best in the industry, not to mention D-1 is an industry pioneer in this aspect. The ability to change and move the jets around and also the ability to adjust each jet at the jet face allows for an unlimited amount of massage combinations As far as quality, D-1 is top notch. The dealer I work for has been selling D-1 Spas for over 15 years. We simply don't have major problems with the product, we've only had one spa tech during this time period as well b/c they simply don't break down. I'd say that's a very good track record for the 4000 or so spas we've sold over that time period.
